LENS-CLIP.

Specification of Letters Patent.

Patentedheh. 29, I916.

Appiication filed March 2'7, 1915. Serial No. 17,429.

To allwiwm it may concern:

Beit known that I, Gnoncn H. DAY, a citizen of the United States, residing at Southbridge, in the county of. Worcester and tate of Massachusetts, have invented certain new and useful Improvements in Lens- Clips, of which the following is a specification.

This invention relates to improvements in ophthalmic mountings, and more particularly to a new and novel construction of lens clip.

The ultimate purpose of the invention is to construct a lens clip which is extremely simple in construction; which may be secured to the lens without screws or cement, although the latter is preferably used its application; which is neat and attractive in appearance; which is applicable to various shapes and sizes of lenses, and which will efficiently serve the purpose of this invention.

Another object is to provide a clip which may be easily formed on the end of a bridge, thereby materially reducing the cost of manufacture, and providing an extremely simple construction.

\Vith these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In the drawings: Figure I is a fragmentary perspective view showing the application of the improved lens clip to the. lens. Fig. II is a horizontal section on the line II-II of Fig. I. Fig. III is a horizontal section illustrating a slightly modified form of. lens clip and lens. Fig. IV is a fragmentary perspective view of a further modified form of clip. Fig. V is a vertical sectional view illustrating a further slight modification. Fig. VI is a detail perspective view of a temple clip. Fig. VII is a detail perspective view of a slightly modified form of temple clip.

Referring to the drawings by numerals, wherein is illustrated the preferred embodiment of the invention, the numeral 1 designates the lens to which the clip 9. is adapted to be secured. As shown in Fig. I of the drawings, the clip 2 comprises a slightly flat longitudinally curved vertically extending portion 3 for engagement with one side of the lens, a slightly offset horizontally extending portion 4 which extends over the edge of the lens and connects the portion 3 with a similarly formed portion 5 which is disposed in alinement with and parallel with the portion 3' and is adapted for engagement with the opposite side of the lens 1. The portion 3, from the terminal end thereof, extends downwardly upon one side of the lens, has the portion t extending across the edge thereof with the portion 5 extending upwardly on the opposite side of thelens, the upper end of the said portion 5 being extended laterally away from the lens, as illustrated at 6 is then curved downwardly and forwardly as at 7, and then upwardly and arched to form the bridge 8. By this construction it will be seen that the bridge may be formed as an integral part of the clip, that the said clip and bridge may be formed from a single strand of straight material, and that the material may be either of the same size and thickness throughout its length, or may be slightly reduced at its end, as desired.

By slightly flattening the inner faces of the port ons 3 and 5, as clearly illustrated in Fig. II of the drawings, it will be obvious that a firmer grip will be provided between the clip and the lens so that when the cementitious material 9 is a plied to the clip and lens the lens will be firmly held therein.

In Fig. III of the drawings, I ha e illustrated a sl ghtly modified form of clip. Instead of flattening the portions 3 and 5, I l'eave the same circular in shape and provide the lens with vertically extending recesses 6 upon opposite faces thereof, and into which the said port ons 3 and 5 are adapted to be placed. If desired. in this instance the cementit ous material may be dispensed with as the inherent resiliency of the portions 3 and 5 will hold the same in secure clamping engagement with the lens to hold the lens to the clip.

In Fig. IV of the drawings I have illustrated a modified form of clip which comprises a substantially rectangular shaped frame 7 which is slightly curved longitudinally to conform to the curvature of a lens,

and which has the inward portion thereof cut awav as at S to provide a recess in which the bend is adapted to seat, the side walls of the frame being adapted for engagement with either side of the lens, while the upper and lower walls 9 and 10 respectively have the inner portions thereof cut at an angle, as clearly illustrated, in order to permit the lens to be placed between the said side walls. Cement or other adhesive material is then applied between the engaging surfaces of the clip and the lens to firmly secure the lens to the clip, as will be understood.

In Fig. V of the drawings the upper terminal end of the portion 3 is shown as extending over the edge of the lens in a manner similar to the horizontally extending lower portion 4. In this form of the invention the upper and lower horizontally extending portions are cut away as at 10 to permit the lens to be placed between the side portions of the clip. By cutting away these horizontally extending portions it will be obvious that it is unnecessary to bend either the upper or lower horizontally extending portions outwardly in order to permit the lens to be placed between the side portions of the clip.

It will be understood that I may want to utilize the construction set forth to provide clips which will be adapted for connecting the temples of eyeglasses to the lenses. In Fig. VI, I have illustrated a substantially rectangularly shaped frame which may be of any of the constructions set forth, and in this particular form a piece of material 11 is bent into the shape shown and has projecting laterally therefrom adjacent each of its terminal ends a lug 12 which are adapted to receive therebetween the end of the temple.

his clip may be either provided with the cutaway portion 10, as illustrated in Fig. V of the drawings, or may be provided with the offset horizontally extending portions 4, as illustrated in Figs. I and II of the drawings, and may be secured to the lens in any preferred manner.

In Fig. VII of the drawings another slightly modified form of temple clip has been shown. This form comprises a frame similar in construction to the frame illustrated in Fig. IV of the drawings with the exception that it is formed from a single strand of rectangularly shaped material, in

Gopies of this patent may he obtained for five cents each, by

Washington. D. C.

stead of being cast as illustrated in Fig.

IV of the drawings, and is further provided,

with the laterally extending temple pivoting lug l2.

From the foregoing description taken in connection with the accompanying drawings, it is thOHght that the construction and operation of the device will be clearly understood. and while I have herein shown and described one specific form of my invention, I do not wish to be limited thereto, except to such limitations as the claims may import.

I claim:

1. The combination with a regularly shaped lens. of a clip for application thereto formed from a single piece of material and comprising portions lying in engagement with the faces of the lens, but curved to correspond with the curvature of the edge of the lens, and cross connecting portions offset to fit around the edge of the lens and connect the ends of the side portions, said parts being all formed from a single piece of material and a cementitious uniting medium intermediate the inner faces of the clip portion and the edge and faces of the lens for securing the clip in position.

2. A cement attached lens clip for an ophthalmic mounting, comprising a pair of spaced curved members adapted to conform to the curvature of the edge of the lens, said members terminating at each end in outwardly extending portions adapted to pro.- ject beyond the edge of the lens, and terminating in a cross piece connecting the curved members on opposite sides of the lens. the several parts just described being formed from a single'piece of material, a bridging member integral with said piece of material, and a cementitious medium adhering to the inner face of the curved and, connecting members for securing a lens within the clip.

In testimony WhereofI afiix my signature in presence of two witnesses.
